You know most of the time, squatters don't hurt anyone, don't make noise as its often an industrial building that's squatted, and are pretty nice communities to live in (there is an alcohol and unprotected sex issue though). Medium to large communities (often once you have children) can be problematic but it isn't the majority in western countries.
Lol, it really is true that "civilization" is three meals away from being kaput.
